The amount of the extra snow would a child need to take a snowball will be 636.71 cubic cm.
<h3>What is the volume of the sphere?</h3>
Let d be the diameter of the sphere. 
Then the volume of the sphere will be 
V = 1/6 πd³ cubic units
Then the amount of the extra snow would a child need to take a snowball with a diameter of 8 cm and increase its size to a snowball with a diameter of 12 cm will be 
Amount of snow = 1/6 π x 12³ - 1/6 π x 8³
Amount of snow = 288 π - 85.33π
Amount of snow = 636.71 cubic cm

The expression would be 34 - 1.5d
34 ounces minus 1.5 ounces multiplied by d (the amount of days that have gone by.)
        
                    
             
        
        
        
Answer: x^2 + 9x + 20
Step-by-step explanation:
Foil Method: (a + b) (c + d) = ac + ad + bc + bd
Lets say: 
a = x
b = 5
c = x 
d = 4 
Plugging in the numbers: xx + 4x + 5x + 5*4 
Combine like terms: 
xx = x^2
4x + 5x = 9x 
5 * 4 = 20 
You're then left with: x^2 + 9x + 20
